Rana catesbeiana
American Bullfrog
This is an American Bullfrog. I took this picture in April of 2005 with my Sony Cybershot DSC-T1. I originally posted it here. Note the large eardrum and that it is without dorsolateral ridges. The Green Frog-Rana clamitans , like the bullfrog, has a large tympanum, but it has a pair of dorsolateral ridges running down the back which is not seen in the bullfrog.
